Hazards threatening underground transport systems
TL;DR: The importance of studying the water-related hazards in metro systems to fill the gaps in this topic is emphasized, due to the frequency and scope of geotechnical and air quality hazards, which exceed in extreme magnitude the extreme precipitation events that can influence underground transportation systems.

Effect of fire on concrete and concrete structures
TL;DR: There are three methods of assessment of fire resistance: (a) fire testing, (b) prescriptive methods, which are rigid; and (c) performance-based methods which are flexible as discussed by the authors.

Turbulence statistics in a fire room model by large eddy simulation
TL;DR: In this paper, the authors used large eddy simulation (LES) to predict the turbulence structure of the flow and temperature fields due to a fire in the compartment by large-eddy simulation.
The new piarc report on fire and smoke control in road tunnels
TL;DR: In 1992, the Committee on Road Tunnels of the World Road Association (PIARC) set up a working group devoted to Fire and Smoke Control, which dealt with all issues connected with fire and smoke control in road tunnels, including objectives, design fires, smoke behaviour and corresponding study methods, ventilation and other safety facilities, tunnel reaction and resistance to fire, response management.

Simulation of temperature and smoke distribution of a tunnel fire based on modifications of multi-layer zone model
TL;DR: In this article, a modification on Suzuki's multi-layer zone model (MLZ) has been done to predict temperature and smoke distribution of tunnel fires, i.e., the radiation heat loss of fire source is taken into account and a four-surface radiation heat transfer model is introduced.
